FRANK TRAHIN, OF DETROIT, .MICHGAIL ENGiNE-MANIFOLD.

l To Il Ich-om t'mag/ concern,"

g Be 1t known that I, F RANK A. TRAiiiN, a citizen of the United States, and residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved llngine-lllanifold, of which the fol; lowing is a specification.

The present invention relates to a mani-- fold for an` internal combustion engine whereby kerosene or the like may be readily It consists in a combined intake and exhaust manifold wherein the intake passages are surrounded by and -heated from the exhaust passages, together 'with a'stcain generating pipe or passage disposed within and protected by the. exhaust passage, saidsteain pipe havin its end pr tio'ns communicating with the discharge ends of the intake passages; theinvention furtheiwv consists in means for admitting water to the generator at will and substantially in ac cordance .with the normal-demands of the engine; in a primer located-above the 1n- I take end of the intake passage of the maniy fold and cfnnmunicating therewith by a. pipe or the like which passes through theexhaust' passage; and in certain other details of construction shown, described and claimed.

the

. sign is attached to In the drawings, Figure 1 is a side elevation, parts being broken away, s howing .a referred embodiment of the invention.

4ig. 2 is a plan view corresponding thereto, cylinders being omitted.. Figs. 3 and 4 are sections on the lines 3-3 and 4-4, respectively, of Fig. 1, the 'primer being omittedin F1g. 4. Fig. 5 is a longitudinal section showing a preferred' form of connection between the external steam conducting pipes and the fittings therefor.

1 indicates the cylinders of an internal combustion engine-the number may vary, four being shown-andisecured thereto in any suitable way, for example, by bolts (not shown) which pass through perforated bosses or stiifener's 3, is a combined intake and exhaust manifold designated as a whole by 4. A carbureter 5 of any preferred detlie lower side of the manifold by bolts Gand has its mixture. passage 7 in communication with the T-shaped intake passage 8 whereby the combustible mixture is alternately delivered to the cylinder intake passages 9 on opposite sides of the transverse central plane of the engine.4
